Verity MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 74 installs a week from pypi. Last commit 2 Aug 2026.
Fail-closed verify-before-you-act gate for AI agents. Signed receipts. Pay-per-call via x402.
Today is the operative word: we check Verity MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
